Application 'nieja April 9,1919. Serial No. 288,780.

Be it known that I, KENNETH Rosrr'rorr, a citizen of the United States, residing in Philadelphia, Pennsylvania, have invented certain Improvements in Count'erbalances for Locomotive Drivin -Wheels, of which the following is a speci cation.

My invention relates to certain improvements in. co'unterbalances for the driving wheels of locomotives and particularly those having detachabletires. I

The object of my invention is to increase the weight of thecounterbalance by extending it beyond. the body ortion of the wheel and to make it detacha- 1e so that it can be removed when it'is necessary to detach the .tire from the body portion when renewals are necessary.

In the accompanylng drawings: Figure 1 1s a side v ew of a locomotive driving wheel showing my improved counterbalance in place; 7

Fi ig. 3 is a perspective view of the detachable counterbalance.

stance. The hub is extended, as at 5, and is bored at'6 for the receptionof the pin to which the connecting', or parallel, rod is at- 'tachd. 7 is the fixed portion of the counterbalance, which is opposite the projection 5. This portion is ma e hollow, as at 8, in the present instance. 9 is a tire which is forced onto the body portion 1 of, the wheel from the outer side thereof until a lip thereon engages the body portion so that the tire can only be forced onto the body of the.

wheel from the outside.

sary and this counterbalance cannot be ex-' tended laterally on the inside or on the outside of the wheel, as, in one case, it would interfere with the frame, and, in the other case, with the connecting, orparallel, rod.

By my invention, however, I gain the additional weight by extending the counterbalance beyond the periphery of the body portion of the Wheel so as to overlap the tire.

12 is the detachable section of the counterbalancemade as shown in Fig. 3, and having a portion 13 which extends beyond the periphery of .the body portion 1 of the wheel and overlaps the tire 9. I preferably form an internal rib 14 on the detachable counterin the body of the wheel and is secured to the wheel by a series of rivets 16, or other fastenings. The heads of the rivets are countersunk, in the present instance, so that they will be flush with the surface of the wheel and counterbalance. By this construction a considerable weight can be added to the counterbalance without increasing the Width of the Wheel and the section 12, being detachable, can be removed when necesbalance 12, Which-is'adapted to a recess15 saI'y so as to allow for the removal of the rim 9, which is forced ofiof the body portion 'in the direction of the counterbalance.

1 is the body of the wheel having a hub 2, a rim 3 and spokes 4, in the present in It will be understood that the tire can be plain, as shown, or can be flanged, as some driving wheels of alocomotive areplain, while others are flanged.

I-claim: r

1. A driving wheel-for a locomotive having a removable tire and having a detachable counterbalance extending beyond the periphery of the body portion of 1 the wheel and overlapping the tlre so that on the removal of the counterbalancethe tire can be detached from the wheel. v

2. The combination in a locomotive driving wheel, of a body portion having a hub, Heretofore, it has been the usual practice rim and spokes, and having a segmental groove; a tire forced'onto the body portion;

and a detachable counterbalance having a portion extending'beyond the body of the wheel and overlapping the tire and having a flange extending into the groove of the wheel; and means for attaching the counterbalance to the body of the wheel.

3. The combination in a locomotive driv ing wheel, of a body portion having a hub,.

rim and spokes, and having an extension to receive the crank pin and. having opposite to the crank pin a portion of the counterbalance made integral with the Wheel; a tire mounted on the body portion; and a detachable section forming an extension of the integral counterbalance and detachably secured to the body portion'of the wheelso that it can be removed when necessary to 10 I'ClllOVe the \VOI'II tire. v

In witness whereof I aflix my signature.

KENNETH RUsHToN.
